Air Conditioning: Notes
WARNING: This page is about a different car, the 2006 Mercury Grand Marquis and 2006 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.
The A/C refrigerant system is a clutch cycling orifice tube type. The system components include:
- A/C compressor
- Clutch and clutch field coil
- A/C condenser core
- A/C evaporator core
- Suction accumulator
- Connecting refrigerant lines
The refrigeration system operation is controlled by:
- Evaporator core orifice
- A/C cycling switch
- A/C pressure sensor
- A/C compressor pressure relief valve
The refrigerant system incorporates an A/C compressor controlled by an A/C cycling switch.
The A/C cycling switch senses the A/C suction pressure to control A/C compressor operation.
An A/C compressor pressure relief valve is installed in the rear of the A/C compressor to protect the refrigerant system against excessively high refrigerant pressures.
The A/C evaporator core orifice is installed in the condenser-to-evaporator tube to meter the liquid refrigerant into the A/C evaporator core.
